SEGREGATION AND HOMOGENEITY.                          255
TABLE XIII-P. Segregation in Swedish Ingots.
Calculated from Wahlberg: Journal I, and S. I.. Vol. II, 1901. Left-hand figures In each rectangle  surface at top and bottom. Right-hand figures = centre of ingot at top and bottom. Each figure is average of determinations by three chemists. Plain figures = car bon; parentheses in italics = phosphorus.

tion in the top and a slight amount in the center of the bottom, while A showed marked segregation in the top and a considerable amount in the bottom of both carbon and phosphorus. It will be evident that by cutting off the top of the ingot the remainder of the steel will be practically uniform, for the central axis constitutes but a small portion of the finished material.
